“…Our result corroborates those of Rocha et al (2017), that found that the use of Spirulina platensis at low concentrations (1%) provides an improvement in the productive performance and influence on the water use efficiency (E/A) of papaya seedlings. According to Dias, Rocha, Araújo, Lima, and Guedes (2016) studying the application of Spirufert®, a product based on Spirulina platensis, 10 g L -1 applications provide a higher yield of Vol.…”

Seedlings production is one of the most important stages of the production system and directly influences the performance of the plant in the field. In this sense, the present work aims to evaluate the use of biomass doses of Spirulina platensis and Scenedesmus sp. via root system on the production of yellow passion fruit seedlings. A greenhouse experiment was carried out using a randomized block design in a 2 × 5 factorial scheme (Spirulina platensis and Scenedesmus sp., at the doses 0.0%, 0.2%, 0.4%, 0.8 % and 1% m/v), with four blocks and two experimental units per plot. At 60 days, leaf number, total seedling length, shoot diameter, root system length, shoot length, shoot and root fresh mass, dry mass, root dry mass and total chlorophyll were measured. Spirulina platensis showed superior performance compared to Scenedesmus sp., for the variables stem diameter, shoot length, fresh shoot mass, fresh root mass, dry shoot mass and root dry mass. The doses influenced the number of leaves, root fresh mass, root dry mass, shoot length and fresh shoot mass significantly. The best dose of microalga applied was 0.8% in passion fruit seedlings at 60 days.
